DESCRIPTION/ORDERING INFORMATION (CONTINUED)
DROPOUT VOLTAGE
vs
LOAD TRANSIENT RESPONSE FREE-AIR TEMPERATURE
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly
proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the
quiescent current is very low and independent of output loading (typically 85 mA over the full range of output
current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life for
battery-powered systems. This LDO device also features a sleep mode; applying a TTL high signal to enable
(EN) shuts down the regulator, reducing the quiescent current to 1 mA at T
J
= 25°C.
The RESET output of the TPS767D301-EP initiates a reset in microcomputer and microprocessor systems in the
event of an undervoltage condition. An internal comparator in the TPS767D301-EP monitors the output voltage
of the regulator to detect an undervoltage condition on the regulated output voltage.
The TPS767D301-EP is offered in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output
voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The
TPS767D301-EP is available in a 28-pin PWP (TSSOP) package. The device operates over a junction
temperature range of –55°C to 125°C.
